Specification of Letters Patent.

Patented Apr. 14, 1914:.

Application filed November 1, 1912. Serial No. 729,113.

annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

The object of my invention is to provide a strong durable, and yet amply elastic 0r resilient mat, or pad, and capable of economical. manufacture which will be useful in a variety of relations, and to this end my invention consists in the pad constructed substantially as hereinafter specified and claimed.

In the accompanying drawingsFigure 1 is a plan view of a mat constructed in accordance with my invention; Fig. 2 is a detail view in perspective, of a portion, or section, thereof.

In the form in which I prefer to make it, my mat or pad 10 is flat and circular in contour, it being made of a strip 11 that is continuous, and spirally wound. There may be a central hole, formed by a ring or collar 12, about which the strip is wound, and said hole can be of varying size, being larger where it is desired to economize material.

The strip 11, is of some tough and elastic material, such as duck and rubber, and its upper and lower edges are formed each into a tube 13, so that at top and bottom, the mat or pad has a bearing surface composed of a series of concentric circular or spirally extending pneumatic tubes with elastic walls, and the strip between the two tubular edges is flat. As the flat portions of the strip between the tubular edges are separated from each other, it will be seen that the interior of the mat is cellular, or provided with air spaces 14, and hence, for that reason, as well as by reason of the tubular edges, the mat is very elastic or resilient. When made of duck and rubber, the rubber, after being cured, becomes a homogeneous mass, that hermetically seals up the air chambers or cells, and thus confines the air therein. The tubular edge is made by inclosing a rubber tube 15 in the folded over portion of the strip.

Around the periphery of the mat in the spaces between the upper and lower tubes, I

apply a retaining band 16 of suitable material, such as duck and rubber.

Of course, instead of the mat being given a round or circular form, it can be given other shapes.

My mat or pad is useful wherever a cushioned, or elastic support is required, as for example, as an alighting or landing pad for firemen in descending the poles in engine houses, a standing mat for railroad engineers and motormen, a boat seat, etc.

Having thus described my invention what I claim is 1. A mat or pad consisting of a strip of elastic material wound upon itself and having each of its outer edges of tubular form, all the convolutions of said strip being in substantially the same plane.

A mat 0r pad consisting of a spirally wound, continuous strip of elastic material having each of its outer edges of tubular form.

3. A mat or pad consisting of adjacent layers of elastic material having tubular bearing edges on opposite sides inclosing rubber tubes, said layers lying in substantially the same plane.

4. A mat or pad having upper and lower surfaces formed each of a series of tubes, the tubes on one side lying in substantially the same plane, and the two sets of tubes be ing connected by strip-like members.

In testimony whereof I affix my signature in presence of two witnesses.
